WebSphere MQ channel security is not implemented in accordance with security requirements.

An XCCDF Rule

Description

<VulnDiscussion>WebSphere MQ channel security can be configured to provide authentication, message privacy, and message integrity between queue managers. WebSphere MQ channels use SSL encryption techniques, digital signatures and digital certificates to provide message privacy, message integrity and mutual authentication between clients and servers. Failure to properly secure a WebSphere MQ channel may lead to unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of some system services, applications, and customer data.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Refer to the following report produced by the z/OS Data Collection:

- MQSRPT(ssid)

NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). 
1) Find the DISPLAY QMGR SSLKEYR command to locate the start of the Queue Manager definitions.
2) Verify that each WebSphere MQ queue manager is using a digital certificate by reviewing the SSLKEYR parameter to ensure that a keyring is identified.  i.e. SSLKEYR(sslkeyring-id)
3) Issue the following ACF2 command, where ssidCHIN is the lid for the WebSphere MQ Channel Initiator's userid and sslkeyring-id is obtain from the above action:

LIST ssidCHIN PROFILE(CERTDATA, KEYRING)

The output will contain information on the CERTDATA and KEYRING records for the user. Find the CERTDATA entry that has a Key ring name field with sslkeyring-id. Review the ISSUERDN field for this CERTDATA record for the following:

OU=PKI.OU=DoD.O=U.S. Government.C=US
OU=ECA.O=U.S. Government.C=US

NOTE: The Certificate Label Name is case sensitive.

Review the Issuer's Name field in the resulting output for information of any of the following:

OU=PKI.OU=DoD.O=U.S. Government.C=US
OU=ECA.O=U.S. Government.C=US

4) Repeat these steps for each queue manager ssid identified.

To implement the requirements stated above, the following two items are provided which attempt to assist with (1) Technical "how to" information and (2) A DISA Point of contact for obtaining SSL certificates for CSD WebSphere MQ channels:

1. Review the information available on setting up SSL, Keyrings, and Digital Certificates in the CA-ACF2 Security for z/OS Administrators Guide as well as the WebSphere MQ Security manual. Also review the information contained in the documentation provided as part of the install package from the DISA SSO Resource Management Factory (formerly Software Factory).

2. For information on obtaining an SSL certificate in the DISA CSD environment, send email inquiry to disaraoperations@disa.mil.
